Both Search Engine Land and MediaPost picked up on some of the key findings of RKG’s latest Digital Marketing Report yesterday. Pamela Parker at Search Engine Land spotlighted the coming shake-up in the comparison shopping space noting:

The big story of the quarter — Google’s move to monetize Shopping by transitioning merchants to paid listings ads (PLAs) — won’t truly reveal its impact until later in the year. RKG’s figures give some measure of the impact of this change. The company said 15% of its clients non-branded paid clicks on Google were generated by PLAs in the second quarter, and they generated a 13% higher than average return-on-ad-spend (ROAS).

On the desktop, Google improved its share of organic search traffic, which rose from 76% in Q1 to 77% in Q2. Bing and Yahoo each held a share of 10%. In paid search, Google AdWords generated 84% of clicks.

June 2012 search data from comScore reveals that Google holds 66.8% market share for the month, up sequentially from 66.7%. Bing holds 15.6% for June, compared with 15.4% in May, and Yahoo fell 13% from 13.4%, respectively, according to Macquarie Analyst Ben Schachter.
